Hi Odysee
You need to install the virtual devices plugin on your controller first.
There’s an explanation of how to do it on this help page:
Recreate Vera ‘House Modes’ using Meshbots - help.mios.com (ignore the topic of the tutorial, you just need the plugin bit).
…there’s also a community thread on it here - How to - Create virtual devices on Ezlo platform
Thanks
Paul
